I believe it was 5, not sure though, if u remember the matrix itself I can tell you for sure

Yyayaya I got just the SAME Thankyou for confirmation

&&& What was the value of x of that stretch ,factor 3 in matrices at the last page

yes it is 5

ow about the Scale which is 1/10 of the real car.. What was the windscreen area of 135?

 

[Hamzeh S]

yaa

 

[~`Heba`~ :)]

I got the gradient -1.25

 

[Hamzeh S]

samee

The windscreen and the real car thingii.. It makes a mould of 1/10 of the real carr.. Something like that and what was the windscreen area of 135 and the other qstn of 408000

 

[beewhiz997]

the probability ya it simplifies to 13/15 and the gradient always has a range i got -1.25 some got 1.1 i think a range of 1.05-1.45 or 1.5 is the answers

no the probability is 7/12?!

I got the gradient -1.25

The EXACT value for the gradiant is -1.5, there a way to do it by the calculator, so I think your answer falls in the range

 

[Hamzeh S]

noo it was 52/60 so it simplifies to 13/15

ow about the Scale which is 1/10 of the real car.. What was the windscreen area of 135?

the answer is 13500

 

[Diablo]

no the probability is 7/12?!

Its 13/15

 

[beewhiz997]

noo it was 52/60 so it simplifies to 13/15

but i did 50-15 /60 coz it says who got more than 16

 

[beewhiz997]

Its 13/15

ok how...can u write d steps?

 

[Hamzeh S]

u should decrease 60 from 8 i forgot the questions :S

 

[Hamzeh S]

u just measure from the point he asked and see what it equals on the y axis and decrease it from 60 because 60 is the total so it 52 trees which are loger so 52/60

 

[Lostsoul]

Its 13/15

I got the samee

 

[Lostsoul]

the answer is 13500

Pheww.. Got that and what was the next one? The 408 one?

 

[beewhiz997]

oh well....me n my friends all got it wrong then so got 7/10, etc but no one got 13/15

Yup guys in the first functions i formed the functions but forgot to multiply the square of it with itself again so i can get a cube its out of 2 the questions will i get 1 mark for 2 correct steps ?
